Description
STiD128 is STMicroelectronics’ next generation
front-end device for interactive cable gateway and
set-top box applications. STiD128 can also be
used standalone for cable modem application.
STiD128 provides a solution for operators to
specify a range of very high-performance
DOCSIS 3.0 STB, multimedia gateway or cable
modem platforms.
A total of 16 demodulation channels can be used
for DOCSIS out of which 8 channels can be used
as video channels. Allocation of the channels is
flexible.
A powerful dual core CPU allows telephony and
data distribution including routing/switching and
firewalling.
